My tester does the usual build binutils, minimal gcc & target libraries,

I should have something close locally then, thanks.
Sounds good. Other than using qemu to bootstrap weird dead platforms like
m68k, alpha, hppa, etc I don't think it does anything special/unique.
Hello,
I've had some urgencies I needed to attend to, but I can restart work on this.
I'm having trouble making sure I'm running all relevant tests. Can you share
the command line or lines you use to run the testsuite ? Thanks.
So my tester builds a dummy simulator that always returns success. That
lets me at least verify the code generator isn't triggering internal
compiler errors, verify the generated code can be assembled & linked.
Obviously with a dummy simulator it can't actually test the resulting
code for correctness.
Assuming you're in your gcc object subdirectory I use
make -j <whatever> check RUNTESTFLAGS="--target_board=c6x-sim"
You'll need a c6x-sim.exp in your dejagnu boardsboards directory. I've
attached mine.
